Balance-2: Using the data from the prior problem, obtain 90% confidence interval for the left foot up data. a
Problem 22.5Balance-3:Examine the Left Foot 90% and 95% confidence intervals from the prior problems. What happened to confidence and precision when going from a 90% C.I. to a 95% C.I? Explain why this happens?
Problem 22.6Balance-4:The N = 94 statistics table to the right presents the mean, μ, and standard deviation, σ, for the studied population. Review the means and determine if they fall within the 95% confidence intervals generated in the previous problems for the samples of size n = 30. So, can samples be used to estimate population parameters? What would be some advantages of using samples to estimate population parameters?
